CNMG160612-RP5 WPP20G — Turning indexable insert, Tiger‑tec Gold, RP5 chipbreaker (Walter Tools)

A CNMG160612-RP5 WPP20G turning insert designed for productive turning of Stahl components, combining a coated carbide grade with a robust chipbreaker for consistent machining performance

• CNMG 80° rhombic geometry
• Tiger‑tec Gold coated carbide grade
• RP5 chipbreaker for reliable chip control
• Negative 0° rake with 1.2 mm corner radius

Increased productivity through advanced coating and grade

The combination of the Tiger‑tec Gold technology and the WPP20G grade provides a balance of wear resistance and toughness that supports longer tool life and fewer insert changes. The coating improves thermal resistance during extended cuts, which reduces downtime and contributes directly to higher machine availability. This benefit is particularly relevant in batch production and series turning tasks where steady cutting conditions translate into predictable throughput. The CNMG geometry also helps maintain cutting stability when changing from roughing to finishing passes.

Consistent chip control and surface quality

Thanks to the RP5 chipbreaker and the rhombic 80° geometry, the insert creates controlled chip formation that eases chip evacuation and reduces the risk of built-up edge. Controlled chip flow improves component surface quality and minimises secondary operations. The negative 0° rake angle provides stronger cutting edge support in interrupted cuts, while the 1.2 mm corner radius contributes to a robust corner that resists edge chipping during heavier engagement. These features lead to repeatable results and less scrap in daily production.

Optimised for Stahl turning applications

This grade is specified for machining Stahl, addressing the thermal and mechanical behaviour typical of unalloyed and alloyed steels. The coated carbide substrate supports medium to high cutting speeds and offers a consistent balance between wear resistance and toughness, which is advantageous when working across a variety of steel alloys. The insert’s tolerance class M ensures interchangeability and reliable seating in standard toolholders, simplifying tool management across toolrooms and production lines.

Practical handling and process advantages

The CNMG form and the standardised designation make tool selection straightforward and reduce setup time. With the clear specification of chipbreaker, radius and rake, process planning becomes simpler and tool lists remain concise. The insert supports efficient inventory rotation and is compatible with common toolholder systems that accept CNMG geometry. For applications requiring verification or adaptation of cutting data, the Metav Werkzeuge team can assist with process parameters to match material grades and machine capability.

FAQ

What materials is this insert suitable for?
The CNMG160612-RP5 WPP20G insert is specified for machining Stahl and is optimised to handle the typical heat and chip formation behaviour of unalloyed and alloyed steels.

How does the RP5 chipbreaker benefit machining?
The RP5 chipbreaker promotes consistent chip formation and evacuation, reducing the risk of entanglement and improving surface finish when using the CNMG160612-RP5 WPP20G insert.

Is the 1.2 mm corner radius suitable for finishing passes?
A 1.2 mm corner radius provides robust edge strength and is suitable for both semi-finishing and finishing in many Stahl turning operations, offering a compromise between edge durability and surface quality.

What does the WPP20G grade mean for tool life?
The WPP20G grade, part of the Tiger‑tec Gold series, balances wear resistance and toughness to deliver extended tool life in a range of Stahl applications under typical turning conditions.

Can the insert be used in interrupted cuts?
Yes, the negative 0° rake angle and the robust corner radius make this insert well suited to interrupted cutting situations where edge stability is critical.
